I'm not finished with the DIY, b/c there may be some diagnostic work needed...dropping off tomorrow to determine the details. However, I'm far enough along that I can provide you all with the CHECKLIST. I made this AFTER my install as during the install I was fumbling with pages. It's basically the quick version of the DIY, really meant to ensure you don't forget something...OR for advanced installers just needing a quick list of tasks.
DISCLAIMER: This Checklist is for REFERENCE ONLY and serves only as backup to help ensure all steps have been addressed. See DIY for full details. This procedure represents one method of installation on a specific vehicle and is shared/posted for **REFERENCE ONLY**. [COLOR="Red"]This procedure requires **CAUTION** as it involves heavy loads and stored potential energy that could cause serious personal injury and/or vehicle damage if mechanical disassembly and/or assembly is performed improperly. [/COLOR] Use extreme caution and all applicable safety processes when working on your vehicle. This procedure is based on a collection of other DIYs as referenced in the Reference Section of the DIY, as well as ISTA.
CHECKLIST NOTES:
- 2013 E70 X5M
- Checklist based on a complete and consecutive Dinan Spring Install from front to rear axle.
- NORMAL POSITION TORQUE: Place vehicle in ‘normal position’ per ISTA. Otherwise, for consideration: For those fastenings called out to be torqued in normal position, note that the rear fasteners in this DIY can be accessed with the wheels mounted and vehicle on the ground. For the front axle, this is not easily the case. To put front axle in normal position, consider placing jack stands under lower control arms and fully loading suspension to simulate torquing in ‘normal position’.
PRE-INSTALLATION (Prior to Jacking)
☐ (optional) Record ride height for reference
☐ Position vehicle with steering straight ahead
☐ (optional) Fold mirrors to decrease obstructions around vehicle
☐ Ensure emergency brake is OFF
☐ In engine bay, remove left and right microfilter housing covers and right microfilter housing
☐ In engine bay, loosen left and right partition walls and rotate toward vehicle center for access to front strut housing.
☐ In trunk, disconnect negative battery cable
☐ In trunk, for vehicles without third row seating, lift trunk lid and remove carpet trim to access rear strut top mounting bolts.
☐ Jack vehicle, place jack stands, and remove wheels. If jacking one axle at a time, use wheel chocks as necessary.
☐ Place removed wheels under vehicle side skirts as additional safety backup.
FRONT AXLE
☐ Rotate hub/disc rotor so that concave indentions point in vehicle forward direction or OEM marked surfaces point upwards. Mark rotor/hub orientation so that if the driveshaft uncouples from the final drive and the rotor/hub is unknowingly rotated, you know the approx. orientation of the hub to reinsert driveshaft.
☐ Remove hydraulic brake line clamp with pliers and uncouple grommet/line from strut brake line bracket.
☐ Decouple EDC connectors and cables to allow untethered strut removal from vehicle.
☐ Support lower control arm with hydraulic jack, using wood spacers as needed.
☐ Remove Stabilizer Link from Swivel Bearing. If needed adjust hydraulic jack to unload sway bar for link removal. (18mm Box Wrench and T35 Torx Socket)
☐ Disconnect Swivel Bearing from Upper Control Arm. (16mm Socket and Box Wrench)
☐ Consider tethering Swivel Bearing as it becomes unwieldly and naturally leans outward and can disconnect drive shaft from final drive.
☐ Remove Strut Shock Assembly to Spring Strut Holder Bolt and loosen clamping mechanism between Shock Assembly and Spring Strut Holder using expanding tool. (16mm Socket and Knuckle Expanding Tool)
☐ At Lower Control Arm disconnect Spring Strut Holder by removing Bolt and Nut. (21mm Socket and Wrench)
☐ With Suspension in lowest position, separate Spring Strut Holder from Strut Assembly.
☐ In Engine Bay, with Strut Assembly supported beneath, remove three Nuts at each strut tower.
☐ Remove Strut Assembly downwards out of wheel arch. Record photos capturing relative position of OEM components for future assembly of stock configuration. (13mm Socket)
☐ Using Spring Compressor Tool per manufacturer instructions, slowly compress OEM Coil Spring, remove Strut Nut, and slowly decompress OEM Coil Spring for spring removal. (18mm Strut Nut Socket Tool and 6mm Allen Wrench)
☐ On bench, install Dinan Auxiliary Pads and new strut components onto Strut Assembly.
☐ Using Spring Compressor Tool per manufacturer instructions, with Strut Assembly and Dinan Coil Spring mounted, slowly compress Dinan Coil Spring, until strut nut can be installed and torqued. Slowly decompress Dinan Coil Spring. (18mm Strut Nut Socket Tool and 6mm Allen Wrench; M12 Nut 48Nm)
☐ Insert Strut Assembly with Dinan Coil Spring into strut tower and install three new nuts. (13mm Socket; M8 Nuts 28Nm)
☐ Install Upper Control Arm to Swivel Bearing (M10 Nut 56Nm)
☐ Install Stabilizer Link to Swivel Bearing (M12 Nut 100Nm)
☐ Install EDC Connectors and route cables.
☐ Install Brake Line Clamps
☐ Place vehicle in ‘normal position’ per ISTA. Consider using hydraulic jack, position jack stands under lower control arm and load suspension to mimic ‘normal position’. First torque Lower Control Arm to Spring Strut holder Bolt. (21mm Socket and Wrench; M14 Bolt 165Nm in Normal Position).
☐ Then, in ‘normal position’, torque Spring Strut Holder to Strut Assembly. (16mm Socket; M12 Bolt 81Nm, Torque in Normal Position)
☐ Return vehicle to nominal lifted configuration using hydraulic jack and jack stands.
Front Axle Complete.
REAR AXLE
☐ Partially detach rear wheel fender linings (or remove rear bumper) and disconnect VDM cable routing and plugs at connector box to allow strut removal from vehicle.
☐ Remove hydraulic brake line clamp with pliers and uncouple grommet/line from strut brake line bracket.
☐ Remove Bolt connecting Shock Absorber to Control Arm. But first support wheel hub or control arm with hydraulic jack to unload bolt, then remove. (21mm Socket)
☐ Supporting Strut Shock Assembly from underneath to prevent it from falling out, remove three nuts from strut tower in luggage compartment. (16mm Socket) (Requires new sealing grommet at installation).
☐ On bench, disassemble Strut Assembly by removing strut nut. (18mm Strut Nut Socket Tool and 6mm Allen Wrench)
☐ Replace OEM Auxiliary Pad with Dinan Auxiliary Pad, install new components, and reassembly Strut Assembly. (18mm Strut Nut Socket Tool and 6mm Allen Wrench; M12 Nut 34Nm)
☐ Insert Strut Assembly into strut tower and install three new nuts. (16mm Socket; M10 Nut 56Nm)
☐ Adjust hydraulic jack as needed to insert bolt into Lower Control Arm and Strut Assembly. Hand Tighten in place.
☐ Reconnect EDC Connectors and route cables. Re-install fender linings.
☐ Install Brake Line Clamp
☐ Remove OEM Sensor Rods. (10mm Socket)
☐ Install Dinan Sensor Rods that have been each set to a length of 70.05mm (M6 Nut 8Nm)
☐ Mount front and rear wheels and lower the vehicle in reverse order of raising (17mm Socket; M14 Nuts 140Nm)
☐ Torque Lower Control Arm to Strut Assembly loaded Bolt. (21mm Socket; M14 Bolt 165Nm in Normal Position)
Rear Axle Complete.
FINISHING THE INSTALL
☐ Confirm Torque of all Fastenings
☐ Install Engine Trim in reverse order of disassembly
☐ Install Trunk Trim in reverse order of disassembly
☐ Reconnect negative battery cable in reverse order of disassembly
☐ On vehicles with BMW Active Front Steering (AFS), set Steering Angle:
-Start Engine
-Turn steering wheel left to full lock.
-Turn steering wheel right to full lock.
[COLOR="Magenta"]TBD - As needed perform (diagnostic system needed):
☐ Perform 4-wheel computerized alignment
☐ Headlight Adjustment
☐ Ride Height Calibration
☐ Vertical acceleration sensor adjustment[/COLOR]
NOTE: If possible, allow Dinan coil springs to settle a few days prior to ride height adjustments.
END.
[COLOR="Blue"]==================>[/COLOR]
[COLOR="Blue"]The DIY is about 40 pages, including the checklist above. It includes a torque table, the required parts needing replacement (per ISTA), a tools list, and lots of figures and explanation. Most will not likely want or need all this info, but it will be available. I reviewed all the suspension DIY's I could find and referenced them and their links, coupled with procedures from ISTA. Once I'm finished I'll offer to post the PDF.
